equality. Prefer EXPECT_EQ(foo, Full) over EXPECT_TRUE(foo.isFullSet()) because
the former will print out the contents of the constant range that failed.

This can break when there are implicit conversions from types raw_ostream
understands but std::ostream doesn't, but it increases the number of cases that
Just Work.

means that raw_ostream no longer has to #include <iosfwd>. Nothing in llvm
should use raw_os_ostream.h, but llvm-gcc and some unit tests do.

all values belonging to the intersection will belong to the resulting range.
The former was inconsistent about that point (either way is fine, just pick
one.) This is part of PR4545.

A full set is a constant range that represents any number. If you take the
umax of that and [5, 10) you end up with [5, INT_MAX] because the values less
than 5 would be umax's against a value which is at least 5.

merge the new functionality and unittests into ConstantRange. Thanks to
Nick Lewycky for pointing out that it isn't necessary to have two separate
classes here.

what ConstantRange does for unsigned integers. Factor out a
common base class for common functionality.
Add some new functions for performing arithmetic on constant
ranges. Some of these are currently just stubbed out with
conservative implementations.
Add unittests for ConstantRange and ConstantSignedRange.
